MATLAB: Pass part of structure field name to function
Tag : matlab , By : Jonathan Bernard

I hope this helps . I need to pass a part of a structure's name into a function. , How about using a helper function such as
function rec_stru = recSA(stru, field_names)
if numel(field_names) == 1
    rec_stru = stru.(field_names{1});
else
    rec_stru = recSA(stru.(field_names{1}), field_names(2:end));
end
mat{n} = systems.(sysNames{n}).stats.equityCurve.relative.(feeString{n});
mat{n} = recSA(systems.(sysNames{n}), {'stats', 'equityCurve', 'relative', feeString{n}});

Matlab with external C++ function: coder.ceval pass a structure to a function

should help you out I found the solution. I had to include the c header use_struct.h in the use_struct.cpp also with:
extern "C"
 {
   #include "use_struct.h"
 }

Matlab: modifying one field of defined structure in other used function

seems to work fine Variables modifed within a function do not change outside of the function. You should return data as the output of function ul. For example:
function data=ul(data,m)
data.Aeq(m,m) = 1
end

n = 4;
data = struct();
data.Aeq = zeros(n);
data.beq = zeros(n,1);
m =3;

data = ul(data,m)

How do I structure a class or a function/method (or interface) so that as part of a using, I can pass values in the {} b

it should still fix some issue How do I structure a class or a function/method (or interface) so that as part of a using, I can pass values in the {} brackets? , You code is completely valid. You can write your use clause as:
public class SomeClass: IDisposable
{
    public SomeClass(object somevalue) {
    }

    public int AnotherValue { get; set; }

    public int AdditionalValue { get; set; }

    internal void ImHere() {
        throw new NotImplementedException();
    }

    public void Dispose() {
        throw new NotImplementedException();
    }
}

static void Main(string[] args) {
    object somevalue = null;
    using (var something = new SomeClass(somevalue) { AnotherValue = 1, AdditionalValue = 2 }) {
        something.ImHere();
    }
}

How to pass structure field name to function?

help you fix your problem I have many similar function calls dealing with one structure, but each call is using different field of structure. , option 1 - offsets
You can use memory offsets.
void doJob (int offset){
    //some code
    S s;
    int v = *(&s+offset*sizeof(int));
    //some code
}
doJob(0);//i1
doJob(1);//i2
doJob(2);//i3
if(offset>2||offset<0){
    //some kind of error
}
#define I1 &getFieldI1
#define I2 &getFieldI2
#define I3 &getFieldI3
doJob(I1);
doJob(I2);
doJob(I3);
